Process 1:
Battery removes 3 electrons from a gold atom...So you can see that the electrolyte (sodium chloride) is not self replenishing as in silver and that as the chloride diminishes, the hydroxide increases. which is the second process consuming current.
Process 2 detail from process 1:
...(cathode reaction)...(hydrogen gas bubbles off)...(anode reaction) (oxygen gas bubbles off)
Since there is no way for us to know how much current is actually going into each of the two separate processes, we cannot apply Faraday's law to the problem. Further the ratio of current to the two processes constantly changes.
Uh huh. Chemistry...I can't imagine why I didn't make a career out of it.
On a side note, 40 ppm is the weight of the particles divided by the weight of the water. Since gold is approximately twice as heavy as silver and the size of a gold atom is approximately the same, 40 ppm gold has approximately the same number and size of particles as 20 ppm silver.
Hmmm, simple-ish. I just need a stoichiometry review class.
Thanks very much for that WG! Sounds like a bottle of AuCl3H solution plus a few volume/weight calculations and I'm off to the races, one of these days. I'm still trying to figure out what happened to 3 L of electrolyzed (5-hours) colloidal gold and why it didn't happen to todays 1 L of electrolyzed colloidal gold (done in 1-hour and looking good 12 hours later).
I've acquired some 37% HCl and 29% H202. I might just apply them to 1.5 gms of one of my two gold electrodes (0.5" x 2" sheet) - see if I can make my own gold chloride since the getting it in this country requires ordering (some not pharmaceutical/food-grade quality) from China. Gold, however, i$ plentiful.
